While the most produced species of coffee is called Arabica, what is the other type of coffee called, containing twice the caffeine?

Robusta coffee is coffee made from beans of the plant Coffea canephora, which is a more sturdy species than Arabica. Robusta coffee is known for its stronger flavor and higher concentration of caffeine, and is commonly used in instant coffee, espresso, and as filler in coffee blends.
